A. B. C. D.C.
The correct answer is C. Arrow Diagramming Method.
The Arrow Diagramming Method (ADM), also known as the Activity-on-Arrow (AOA) method, is a project management technique that uses nodes and arrows to represent activities and their dependencies.
In ADM, the nodes represent activities, and the arrows represent the dependencies between them. An arrow connects two nodes to show that one activity must be completed before the other can begin. The length of the arrow is not significant, and the arrow can be straight or curved.
ADM is useful for identifying the critical path of a project, which is the sequence of activities that must be completed on time to ensure the project is completed on schedule. The critical path is determined by analyzing the network diagram to identify the longest path through the activities. The critical path is important because any delay in completing an activity on the critical path will delay the entire project.
The other techniques mentioned in the question are also used for activity sequencing in project management:
A. Critical Path Method (CPM) - CPM is a project management technique that uses a network diagram to identify the critical path and calculate the project's duration. Unlike ADM, CPM uses boxes to represent activities and arrows to represent dependencies.
B. Critical Chain Method (CCM) - CCM is a project management technique that focuses on managing uncertainties in the project schedule. CCM adds buffers to the project schedule to account for uncertainties and delays, and uses a network diagram similar to ADM and CPM.
D. Gantt Chart Method - Gantt charts are a visual representation of the project schedule that show the start and end dates of each activity. Gantt charts do not show dependencies between activities, so they are not as useful for activity sequencing as ADM, CPM, or CCM.
Overall, while all the techniques mentioned can be useful for project management, ADM is the only one that uses nodes to symbolize the dependencies of each activity.
